This invention relates to a sander, sand spray or distributor generally. It is particularly aimed to provide a novel means to supplant the present hand method of distributing sand, ashes, cinders, fine stone, or the like overiicy pavements in order to minimize the danger of slippage of pedestrians. The invention however is capable of use as a distributor generally however as for seed, fertilizer and various other materials.

A particular object is to provide a novel means for distributing the sand or equivalent so that the sand will bound from the apparatus in a lively spray, depositing in an even layer upon the ground.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodment.

In said drawings:-

Figure 1 is a view in side elevation of the apparatus;

Figure 2 is a plan view thereof;

Figure 3 is an enlarged detail sectional view taken on the line 3-3 of Figure 2;

Figure 4 is an end elevation of the apparatus;

Figure 5 is a detail section taken on the plane of line 55 of Figure 3; and

Figures 6 and '7, detail the clutches and pin connections between the axle and wheels, being taken on the line 66 and |-'l, respectively, of Figure 5.

Referring specifically to the drawings wherein like reference characters designate like or similar parts, a suitable frame is provided as at IU, preferably endless and made of metallic pipe or tubing, or otherwise, having horizontal portions H, a raised handle bar section or portion at I2 and a lowered forward portion l3 on which a pair of small wheels [4 are journalled, being held in position between couplings l5 and pins or pegs I'G.

Bolted as at I! to the side portions II are side plates l8 which are also bolted as at l9 to a hopper or container 20, preferably having its front and rear walls downwardly and inwardly inclined as shown in Figure 3, the hopper normally being closed by a cover 2| hinged or pivoted to the hopper as at 22. Said hopper 20 is adapted to contain the sand, crushed rock, cinders or other material to be distributed.

The lower portions of the plates l8 extend below the hopper 20 and are in the form of bearings 23. A main or distributor shaft is shown at 24, disposed beneath the hopper and having axle portions 25 at opposite ends thereof and of reduced diameter. A pair of large ground-wheels 26 are mounted on the axle portions 25, secured against displacement by cotters 21 or the like. The hubs 28 of the wheels 26 have cut-out portions 29 about the axle portions 25, provided with arcuate walls at 30. Coacting with these cut-out portions29 are pins 3 I, which are slidable in openings 32 arranged diametrically of the shaft portions 25. The cut-away portions 23 and pins 3| constitute clutches that cause the shaft 24 to turn unitarily with the wheels 26 as the device moves forwardly but permits the wheels to slip past the pins on backing or reverse movement of the wheels, so that the shaft 24 will not turn therewith.

Attention is called to the fact that the tread or periphery of the wheels 25 is dished to provide relatively close projecting portions 33, or such periphery may be otherwise roughened or irregular so that the machine will constantly jar as it is pushed along, aiding in the agitation and discharge of the sand or the equivalent.

Braces 34 are connected at opposite ends to the frame In and at 35 to the sides of thehopper.

The bottom wall of the hopper is shown at 36, having a row of equidistantly spaced discharge openings therethrough adapted to register with discharge wells or depressions 38 in the periphery of the shaft 24. And an intermediate bar 39 is provided having openings 40 therethrough registering with the openings 31. A plate 4| integral with or otherwise secured to the bar 39 extends downwardly and forwardly therefrom, being equipped with braces at 42 bolted or otherwise fastened as at 43 to the portions ll of frame [0. In the line of discharge of the sand or the like, that is in line with the wells 38, raised portions 44 are provided on the plate 4 I Attention is called to the fact that the openings 31 are in rows in which the wells 38 of successive rows register with alternate openings 31, to avoid too rapid a discharge of the sand and assist in obtaining the desired spray, it being clear that the sand or other particles discharged by the wells engage and bound on the elements 44, assisting in producing the desired spray forming an even layer over the ice or the like. It will be noted that said member 44 are of ovolo shape. Since the sand or other material is of such density as to rebound when striking a hard or solid object, such rebound assists in producing the able over the bottom of the hopper, guided by brackets 46 bolted or otherwise secured at l9 to the hopper. Said valve plate has openings 48 therein adapted to register with the openings 31.

Such plate has a bracket 49 fastened thereto to which a resilient latch arm 50 is fastened at 5|, such latch arm passing through an enlarged opening 52 in a guide block 53 to which the latch arm is pivoted as at 54. Such latch arm' is adapted for engagement'in suitable notches 55 of a bracket 56, to hold the valve plate 45 in position aligning the openings 48 and 31 or closing the latter openings. It will be realized that the plate 53 and bracket 56 are suitably secured to one side of the hopper 20. An operating handle 51 is preferably provided on the latch rod 50.

It is clear that the device may be made of any I desired material and in any desired size. Since the present embodiment merely shows operation 48, 31, wells 38 and onto the striker blocks 44, bounding therefrom in a spray and depositing evenly upon the ice or surface being sanded. When it is desired to cease sanding, the latch rod 50 is operated to dispose imperforate portions of the valve 45 over the openings 31. When adjacent a curb or other obstruction, the handle bar l2 may be depressed so as to place the wheels l4 beyond the. curb or upon the higher plane, and the remainder of the device lifted as an aid in moving over the curb or obstruction.

Various changes may otherwise be made.

I claim as my invention:

An apparatus of the class described comprising a frame, plates on said frame provided with bearings at their lower ends, a. distributing shaft between the plates having axle portions journaled in said bearings, a. hopper fastened to the plates above said shaft, ground wheels engaged with said axle portions, means onto which sand or the like is dropped by the distributing shaft so as to rebound in a spray, said means comprising a forwardly inclined plate, said plate being spaced from and mounted directly underneath said distributing shaft, and striker elements-on the last mentioned plate for engagement by the said sand or the like of substantially ovolo form.
